Lunch Time at Oak Ridge

Let’s sit over here. Gollly the place is packed today. I’m glad we got here before the crowd really got big.

What’s going on anyway?

I dunno, some big conference on a new gadget. All the bigwigs and brainiaks are here. Can’t believe they’re going to eat in here with us. Kinda puts the cramp on our noon card game.

Ha don’t you think they want to join.Not with a cheater like you playing. Your reputation is well known. I still don’t understand why I keep playing with you. Man there’s barely room to sit in here. Hey over there with Schmitt. He’s got some room.

Hey Schmitty how’s it going? You got some….Jeesus what was that?

Holy crap! Something exploded by the kitchen. Can’t see much through the dust….Hey Bill what’s going on?

You know as much as I do Pete. Wasn’t that big of an explosion … maybe one of the cooks let the gas build up in the stove or something. Wait I can see where it happened. It’s overhead in the air ducts. See by the wall there.

OH yeah nice little hole. What the hell could have done that? HEY DAVE ARE WE SUPPOSED TO EVACUATE OR WHAT?

CAN’T HEAR YA. I’LL COME OVER THERE.

I said are we supposed to evacuate or something?

Well no alarms yet. Kind of a small explosion. Maybe a little gas got up in the air ducts somehow.

LISTEN UP EVERYBODY…NO REASON TO PANIC BUT LET’S EVACUATE THE AREA UNTIL WE FIGURE OUT WHAT CAUSED THE EXPLOSION. NO ONE WAS HURT. TAKE YOUR LUNCHES WITH YOU IF YOU WANT AND EAT IN THE AUDITORIUM.

Damn straight I’m taking my lunch. I paid 10 cents for this feast and I’m not wasting a mouthful. Let’s go before they change their mind.

Lucky that gas leak or whatever it was didn’t do more damage. Sounded like a big firecracker. Who in the hell would do something so stupid?

Maybe it was one of the circulation fans……no I don’t think that’s it. They’re still working see how that dust is blowing around. Huh it wasn’t a fan.

2 HOURS LATERIn the head of security’s office

It appears to have been a very small explosion set off by a cheap wrist watch as a timer. We just heard that a similar thing happened in Dayton in the middle of their big conference in the auditorium just before they were about to break for lunch. Same type of thing a small explosion that sent a dust cloud from the air ducts circulating. Funny thing about both explosions was there wasn’t that much dust in the other air ducts. These are all pretty new buildings and it was strange.

Anyway HQ has ordered a lockdown of both facilities until we find the culprits. We’re going to test everyone for explosive residue etc. on their hands. Both air systems are back up and running and the holes are patched but we’re going to keep everyone in place for at least 24 hours until we find out who was responsible for this … prank. I don’t know what else to call this. Was someone trying to test our security or something? I mean those tiny explosions couldn’t do much damage.
